Our Cadillac Extreme Air System was designed to offer the best ride and driving habits while still providing the ultimate slammed stance. The Cadillac system incorporates a front shock and non-binding geometry that eliminates wear, alignment and drivability associated with lesser systems. The system is capable of laying a 29" tall tire and is compatible with factory drum or aftermarket disc brakes. The kit comes complete with upper and lower control arms with bushings, air bag cup, shock relocation brackets, KYB shocks, and adjustable rod end bracket.
